How do I hook up an Ethernet Switch?

1.  HughsNet HN9000 Satellite Modem.  The user guide for this modem indicates it has a DHCP server built-in which assigns IP addresses to your connected computers according to the service plan you have with HughsNet.

Depending upon your needs and service plans, a "switch" might work.  Having said that, you can't go wrong by getting a home router.  In a thread I browsed in a different forum, most if not everyone is using a home router with this modem.  If push comes to shove, you can always just use the back-end switch component of the home router (no configuration necessary - just plug both computers and modem into the "LAN" ports of the router); but I think it would be best used as a router.

Not necessarily.  I have 1 modem and 2 routers and all are DHCP and both routers use the WAN input.  The routers are different makes and have different default IP's.

You are right. Some work right out of the box.

Just thought you all would like to know how I made out with the new router.  I bought a Linksys  WRT160N router and did as Computer_Commando suggested and hooked it up with the directions from a video suggested by Geek-9pm.  I did not use the software that came with the router, just hooked it up and set it up as Windows suggested when it detected a Network.............and it works!!!!!  I am really having a hard time trying to figure out WHY 2 salespersons at Best Buy told me that it was extremely difficult to do and that I would be better off calling the Geek Squad to the tune of $149.00 to set it up.  They really had me spooked at the time.   Anyway, can't thank you all enough for hanging in there with me.  May Santa bring you all the electronic gadetry on your Wish Lists!
